PRESSU RE-REG U LATO R.

SPECIFICATION forming part of Letters Patent No. 472,241, dated April 5, 1892.

Application filed October 24, 1891. Serial No. 409,691- (No model.)

To all whom it may concern:

Be it known that I, WVILLIAM WVERLE, a

citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Pressure Regulators, of which the following, with the accompanying drawing, is a specification.

This invention relates to certain new and useful improvements in pressure-regulators.

The invention has for its object the construction of a device especially designed for brewers use, whereby a uniform gas-pressure within the hogsheads or other closed vessels employed for storing beer or other fermented liquors can be maintained. 7

The invention consists in the peculiar construction, arrangement, and combinations of the various parts, all as more fully hereinafter set forth, and pointed out in the claim.

The drawing represents my improved regulator in central vertical section.

A represents the body of my device, which is provided with an inlet B,having a valve 1).

O is a water-gage.

D is a pressure-gage.

In the top of the bodyA should be provided a suitable opening through which water may be introduced, and this opening should be provided with a suitable plug, as at E.

F is a valved pipe in the bottom of the body A and is for the purpose of drawing off the water when it is desired to clean the device.

G is a pipe the upper end of which is open, but having its lower end closed. This pipe is secured by suitable brackets to the side of the body A.

H is apipe which is adapted to be heldwithin the pipe G, by means of a thumb-screw I, in any suitable and convenient manner.

J is a flexible pipe, of rubber or other suitable material, one end of said flexible pipe being coupled to the upper end of the pipe H, while its opposite end is similarly coupled to the upper end of a pipe K, which projects upwardly from the strainer-plug L in the top of the body A.

In the bottom of the pipe G, I place a quantity of quicksilver M, and I fill the body A nearly half-full with water N.

In practice the inlet-pipe B is connected in any proper manner with the hogshead or other vessel holding the beer or fermenting liquor and the valve 1) is opened. The gas from the hogshead is thus allowed to enter the body Aat the bottom, whence it passes up through the water, the latter collecting and retaining whatever froth may have passed through the pipe B, while the gases arise to the top, pass through the strainer and its connecting-pipes to the pipe H, through which it is forced to the bottom of the pipe G, and before it can escape from such pipe at its open upper end the pressure must have risen to such a degree as to force the gases through the quicksilver. Should the pipe H be immersed too far in the quicksilver and thus cause a greater pressure of gases within the hogshead and which pressure will be indicated on the gage D, then in that event the pipe H is raised vertically and adjusted within the pipe G until the proper pressure is registered by the pressure-gage, as it is very evident that the lesser amount of quicksilver that the gases have to pass through in like degree will the pressure within the hogshead be diminished.

What I claim as my invention is In a device of the character described, the combination of a tight vessel having inlet and outlet, a vertical pipe G, open at its upper end and having its lower end closed, a pipe H, having its lowerend immersed in an ysuitable liquid contained in the said pipe G, a flexible pipe J, connecting the upper end of pipe H with the outlet-pipe K, which latter communicates with the interior of the vessel A, and means for securing said pipe H vertically and adjustably within the pipe G, the parts being constructed, arranged, and operating substantially in the manner and for the purposes set forth.

In testimony whereof I affix my signature, in presence of two witnesses, this 24th day of September, 1891.

WILLIAM WERLE.
